setvar

in skin commands.txt:

"SETVAR" - This allows you to set a global variable in RR. Those variables can be used for simple reference in the skin commands
or be used to toggle between different groups of commands on skins (using BYVAR command).
Example: "SETVAR;APPPATH;C:\MyApp\Myapp.exe"
Then you can reference the variable APPPATH like this: "RUN;$APPPATH$"

Note: SOME (but not all) settings in RR.INI can be changed in runtime.
Note2: You can use ++ in this command when you'd like to delay reference to || on a command or label:
[HL]Example1: Label Code: "$MYLABEL$" -- "SETVAR;MYLABEL;DATE++= ++TIME" (Displays DATE and TIME)[/HL]
Example2: Command Code: "$MYCMD$" -- "SETVAR;MYCMD;AUDIO++PAUSE" (Executes AUDIO and PAUSE)

The highlighted bit does not work. tried it manyy times in many scenarios. just doesnt work.
